Calling SOAP via UTL_HTTP and OAuth2

GJoobSep 26 2024

I am trying to call a Workday SOAP web service from Oracle. I am able to do it from Postman, but anything I try in Oracle just returns the same 500 error message:

"<?xml version="1.0" encoding="utf-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wd="urn:com.workday/bsvc"><faultcode>SOAP-ENV:Client.validationError</faultcode><faultstring>Invalid request</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>"

This is a SOAP call using OAuth2 and I have the access token (Bearer) which is sent as a header.

Does anyone know what I am doing wrong or missing with this code below?

DECLARE

l_http_request UTL_HTTP.req;
l_http_response UTL_HTTP.resp;
l_buffer VARCHAR2(32767);
l_access_token VARCHAR2(32767);
l_soap_body VARCHAR2(32767) := '<?xml version="1.0" encoding="utf-8"?><env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"xmlns:xsd="http://www.w3.org/2001/XMLSchema"><env:Body><wd:Get_Cost_Centers_Request xmlns:wd="urn:com.workday/bsvc" wd:version="v43.0"><wd:Response_Filter><wd:As_Of_Effective_Date>2024-09-23</wd:As_Of_Effective_Date><wd:As_Of_Entry_DateTime>2024-09-23T21:33:15</wd:As_Of_Entry_DateTime><wd:Page>1</wd:Page><wd:Count>100</wd:Count></wd:Response_Filter><wd:Response_Group><wd:Include_Reference>true</wd:Include_Reference><wd:Include_Cost_Center_Data>true</wd:Include_Cost_Center_Data></wd:Response_Group></wd:Get_Cost_Centers_Request></env:Body></env:Envelope>';
l_url VARCHAR2(32767) := 'https://<workday-tenant>';

BEGIN
-- Get the access token
l_access_token := F_GET_TOKEN;

-- Prepare and send the SOAP request
l_http_request := UTL_HTTP.begin_request(l_url, 'POST', 'HTTP/1.1');
UTL_HTTP.set_header(l_http_request, 'Content-Type', 'text/xml');
UTL_HTTP.set_header(l_http_request, 'Content-Length', LENGTH(l_soap_body));
UTL_HTTP.set_header(l_http_request, 'Authorization', 'Bearer ' || l_access_token);
UTL_HTTP.write_text(l_http_request, l_soap_body);

l_http_response := UTL_HTTP.get_response(l_http_request);
BEGIN
LOOP
UTL_HTTP.read_text(l_http_response, l_buffer);
DBMS_OUTPUT.put_line(l_buffer); -- Output the response
END LOOP;
EXCEPTION
WHEN UTL_HTTP.end_of_body THEN
NULL;
END;

UTL_HTTP.end_response(l_http_response);

END;

Many thanks.

Check the error reported in “Control panel→System and Securities→Administrative Tools→Event Viewer” under Windows Log→Application.

How did you set the Instant Client path in PATH? In command prompt?

If you have set it in a command prompt, then make sure you start that command prompt as administrator (i.e. opening it by right clicking on command prompt icon and select “run as administrator” from popped context menu). Also, you should start ODBC data source administrator by executing “odbcad32” from that command prompt. Have you?

pczurak-JavaNet Oct 16 2024

Yes I started the cmd as run as Administrator.

I am using ODBC 64 bit not 32 bit.

I set the path using Windows UI (System properties), and if I open a cmd window and type set I can see the correct path.

starting “odbcad32” from the command line did not help.

I tried the same process on a different computer and got the same results.

Sdhamoth-Oracle Oct 16 2024

odbcad32 is for ODBC 64 bit on Windows x64 versions. You need to start odbcad32 from syswow64 directory to configure ODBC 32 bit on Windows x64 versions.

Have you checked the Application error logs in Event viewer? Did you find any error related to your ODBC application?

pczurak-JavaNet Oct 16 2024

I am running the 64bit version, if I start odbcad32 from syswow64 it starts the 32bit version.

There are no errors in the Event Viewer.

I have tried basic driver version 19.24, but when I click on the Test button, I get the following error:

---------------------------
Testing Connection
---------------------------
Unable to connect
SQLState=S1000
[Oracle][ODBC][Ora]ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

Looks like the service name is missing in your connection string.

Here is a sample of connection string:

sales=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)))
The part that is highlighted with bold characters seems to be missing in your connection string. Fix it.

pczurak-JavaNet Oct 17 2024

This is what I am using.

JDEPRD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = testoda0)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = jdeprd.test.com)
)
)

Are you able to connect to your database using SQL*Plus?

pczurak-JavaNet Oct 17 2024

No:

F:\instantclient_23_5>sqlplus

SQL*Plus: Release 19.0.0.0.0 - Production on Thu Oct 17 07:55:39 2024
Version 19.24.0.0.0

The issue is fixed

In the ODBC Driver Configuration.

For the TNS Service Name you cannot type the name even if you type it exactly as it shows in the dropdown, you must select it from the dropdown, otherwise it won't work.
